AlGaN/GaN HEMT on a free-standing GaN substrate with record 85.2% power-added efficiency at 2.45 GHz
An AlGaN/GaN high-electron-mobility transistor (HEMT) on a free-standing GaN substrate achieved impressive power-added and drain efficiencies of 85.2% and 89.0%, respectively, at 2.45 GHz. We improved the GaN channel quality by reducing the C concentration and eliminated the buffer leakage path by r...
